I Applicationfiled October 8, 1897. Serialll'o. 654,539- (ITo model.)

To all whom it may concern.-

Be it known that 1, PETER BROADBOOKS, a citizen of the United States,residing at Batavia, in the county of Genesee and State of New York,have invented a certain new and useful Improvement in Combined Wire-Shears and Parallel-J aw Pliers, of which the following is aspecification.

My invention relates to a new and useful improvement in combinedwireshears and parallel-jaw pliers, and has for its object to soconstruct such a device that, the pliers shall add great strength anddurability to the wire-shears; and a further object of my invention isto produce a device of this description which shall be exceedinglysimple in construction and efficient in action.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by. the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, formingapart of this specification, in whichFigure 1 is a side elevation of a pair of parallel-j aw pliers having myimprovement combined therewith, the device being closed; Fig. 2, asimilar view, the jaws being open and a portion of the handles beingbroken away; Fig. 3,a dismembered perspective view of the device,showing the several parts which together make up my improvement; Fig.4., a view similar to Fig. 1, but showing an addition thereto of apunch. Fig. 5 illustrates the embodiment of my improvement in a pair ofcut-off pliers; Fig. 6, a detail section of pivoting-stud and Fig. 7 isa top plan view of the form shown in Fig. 4, the handles being brokenaway.

In carrying out my invention as shown, A and B represent the handles ofa pair of pliers, which are let together and pivoted at O, the circularheads being cut away, as indicated at D, for the purpose hereinafter setforth.

E and F are the parallel jaws, which are pivoted directly to the leversat G, and these jaws are slotted at the rear, so as to provide theshanks H, which embrace the heads of the levers andare pivoted theretoby means of the studs I, said studs being set in the handle-levers, so.as to revolve therein, and are flattened at the points extending throughthe slots J, formed in the shanks, the object of which is to present acomparatively large bearing-surface between these studs and the walls ofthe slots and permit the flattened sides of the studs always to lieparallel with the side walls of the slots, as will be readilyunderstood. This arrangement forms an exceedingly rigid joint betweenboth the levers and the parallel jaws, thus preventing the twisting ofeither said levers or jaws when in use, and this is an important featureof my improvement, since heretofore the sidewise strain brought to bearupon pliers and cutters, spring and twist the same to such an extent asvto often resultin the breaking thereof.

Gutters K and L may be secured or formed with the parallel jaws E and F,respectively, and so arranged that they will serve as cutoffs for wireand the like, and it is to be noted that these cutting-jaws are close tothe center fulcrum while the tool is open, so that when said jaws enterinto the metal to be cut the cutters travel or draw away from saidfulcrum and the distance between said fulcrum and the cutters isgreater, so that a wire may be set against the head of the levers and beout without the least outward strain on the cutters, thus obviating thewedging in of the piece out between the cutters and the head of thelevers. The shanks of the parallel jaws lyingin close contact with andcovering nearly the whole surface of the lever-heads, which are pivotedsubstantially, they are not liable to strain or twist by the pressure.

The cut-away portion D of the lever-heads is for a better accommodationof the wire or other article to be operated upon by the cutters K and L.Cut-off dies M may be formed in the rear portion of the heads of thelevers and be utilized for severing small Wire rods.

In Fig. 4 I have shown embodied with the construction just described anoverhanging arm N, pivoted between the shanks of the jaw E by means ofthe pin G, which also pivots the jaw to the handle, said jaw E beingslotted just a little farther forward in this construction than in thefirst-described form. A A rearwardly-projecting extension X is formed onthe arm N and bears against the rounded edge of the lever A, with whichit is arranged eccentrically, as shown in dotted lines in Fig. 4,wherebyit will be understood that when the jaws are pressed together therounded edge will press against the extension X and cause it to operatethe lever N, on the forward end of which is a punch 0, working in thedie I, formed on the upper jaw. It has been found that this combinationis advantageous and that a most powerful punch relative to the capacityof the implement is thereby provided.

The cut-off pliers shown in Fig. 5 consists of the handlelevers Q, whichare pivoted together at R and have pivoted thereto at S the cut-oil?jaws 'l, the shanks of said jaws being slotted and pivoted to thehandle-levers by the studs U, with the same result as that justdescribed, these jaws terminating in the cutting edges V in the usualmanner. Cut-elf dies IV may be formed in both the front and rear of theheads of the levers for the usual purpose. It is to benoted that in thisconstruction the jaws cannot twist, because they move in a direct lineto each other and have more room, so that a wire may be placed nearly tothe center of the cutter.

Of course I do not wish to be limited to the construction here shown anddescribed, as these details may be varied to a considerable extentwithout departing from the spirit of my invention, and the device may beutilized for other tools than those here set forth.

Having thus fully described my invention, what I claim as new and usefulis- 1. In a pair of pliers, two levers pivoted together, parallel jawshaving slotted shanks embracing said levers, said jaws being pivoted tothe levers and also connected thereto by movable studs operating inslots, and cut-off jaws carried by the first-named jaws, as specifled.

2. In combination, a pair of handle-levers let together and pivoted toeach other, apair of parallel jaws, slotted shanks formed therewithadapted to embrace the levers, said jaws being pivoted to the frontportion of said 1evers, revolving studs set in the levers and havingflattened portions projecting through slots formed in the shanks of thejaws, cutoff dies carried by the heads of the levers, and cutterscarried by the parallel jaws, as shown and described.

3. In combination with a pair of pliers of the character described, anoverhanging arm formed with one of the handle-levers, and a die carriedby one of the parallel jaws, substantially as and for the purpose setforth.

4. A pair of pliers consisting of two levers, plier-jaws hinged theretoand means for holding said jaws parallel with each other when the leversare operated.

5. A pair of pliers consisting of two levers, jaws pivoted theretohaving slotted shanks, and studs on the levers projecting through saidslots, as and for the purpose described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses. 7
